Problem
At 60keV, soft tissue attenuates a narrow photon beam 5% more per unit length than water does. Water's linear attenuation coefficient at 60keV is 0.206cm−1.
((a)) Find the linear attenuation coefficient of soft tissue at 60keV.
((b)) Find the half-value layer of soft tissue at this energy.
((c)) A diagnostic X-ray examination sends this beam through 6.0cm of soft tissue. Find the percentage transmitted.
